This book was released on 1978 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Antietam Dam is a 60-foot high masonry structure with an upstream compacted fill embankment with an impervious core approximately 8 feet wide. The dam is approximately 230 feet long with a crest width of 17 feet. The embankment impounds a 16-acre reservoir within a 5.5 square mile drainage basin. The upstream slope is 2.25H:IV, and is riprapped from the crest to elevation 498 with hand-placed stone. The downstream slope is composed of stacked masonry block and has a curved surface, as shown on Plate 5, Appendix E. The dam was founded on trap rock, and does not have a cutoff trench or a grout curtain. There is a 4-foot high parapet wall along the downstream side of the crest. The spillway is excavated into solid rock on the left abutment, and has a skewed spillway with a crest width of 66 feet discharging into a channel which narrows to 30 feet at the end. Thereafter, water discharges into the natural streambed below the dam. The intake tower is located 125 feet upstream from the crest, and contains one discharge pipe, as shown on Plate 5. It is noted that this discharge pipe is no longer operational, and that the reservoir no longer serves as a water supply source. The dam contains a pond drain with a control valve at a valve house located at the downstream toe of the dam.

This book was released on 1978 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fawn Lake Dam is owned by the Lake Wynonah Property Owners Association and is located in South Mannheim Township in Schuylkill County, Pennsylvania. The dam was designed by the original owner, American Realty Service Corporation of Memphis, Tennessee. The embankment was completed on May 12, 1971, and has been in service ever since. The facility is judged to be in reasonably good operating condition. Calculations indicate that the spillway systems are capable of passing the probable maximum flood (PMF). Therefore, the spillway is considered to be 'Adequate'. Seepage was noted emanating from the downstream slope and along the toe of the dam, but there were no indications at this time that this condition is potentially hazardous. No indications of slope distortion, embankment slides or other condition indicative of a potentially unstable embankment were noted.

This book was released on 1978 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Crystal Dam is judged to be in good condition. However, the spillway will not pass the Probable Maximum Flood (PMF) or one-half of the PMF without overtopping. If Crystal Dam should fail due to overtopping, the hazard to loss of life downstream from the dam would be significantly increased from that which would exist just prior to overtopping. Based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway capacity is rated as seriously inadequate. The existing spillway can accommodate a flood with a peak inflow of 37 percent of the PMF peak flow. If the low areas of the top of the embankment were brought up to design grade, the spillway could accommodate a flood with a peak inflow of 61 percent of the PMF peak inflow. The spillway would then be rated as inadequate instead of seriously inadequate.

This book was released on 1980 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: SCS PA 477 is a 52-foot-high, 1,550-foot-long dam. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. About 1,270 feet of the embankment is roughly parallel to U.S. Route 22/Interstate 78. The remaining 280 feet of the embankment forms an angle of about 60 degrees with the highway. The shorter leg contains the maximum section and the principal spillway. The principal spillway consists of a concrete drop inlet riser, a 222 foot long, 30 inch reinforced concrete pipe with eight anti-seep collars, and an impact basin. The emergency spillway was excavated through rock at the right abutment. The grass-lined trapezoidal channel is approximately 150 feet wide and 30 feet wide. The dam and its appurtenant facilities are considered to be in good condition. Calculations indicate that the existing spillway systems are capable of passing the Probable Maximum Flood (PMF) without overtopping. Therefore, the spillway system is considered to be adequate.

This book was released on 1978 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Silver Creek Dam is judged to be in fair condition. The spillway and the low overbanks adjacent to the spillway have sufficient capacity to the Probable Maximum Flood (PMF) without overtopping the dam. Based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway capacity is rated as adequate. The existing spillway and the adjacent overbanks can accommodate a flood with a peak inflow of 115 percent of the PMF peak flow. (Author).

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Park Place Dam No. 3 is a 32 foot high earthen embankment across an unnamed tributary of North Mahanoy Creek. The 685 foot long embankment impounds a 109 acre-foot reservoir within an 0.27 square mile drainage basin. Since very limited data exists regarding the physical features of the dam and appurtenances, most of the features described herein were obtained from field measurements taken during this inspection. The downstream slope was measured to be 2H:1V and is covered with riprap and occasional vegetation, as shown on Photographs 7 and 8. The average upstream slope could not be measured as the very small freeboard between the crest of the dam and the normal pool prevented a reliable measurement. The upstream portion of the slope between the crest and to at least several feet below the waterline was covered with riprap. The crest width ranges from 10 to 12 feet and averages approximately 11 feet wide. A 10-inch water supply pipe is located at the base of the embankment. An eight-inch water supply line branches off in the downstream valve house at the downstream toe. Discharge through both lines is controlled by valves located in the valve house.

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pole Run Dam No. 4 is a 30 foot high earthen embankment across Pole Run, a tributary of North Mahanoy Creek. The 780 foot long dam impounds a nine acre reservoir within an 0.58 square mile drainage basin. Very limited data exists regarding the physical features of the dam. The average measured downstream slope is 2H:1V, and the slope is covered with stone and vegetation. Since the average freeboard of the structure is less than one foot at normal pool level, the upstream slope could not be measured. A portion of the upstream slope is covered with stone, and this stone could be seen to extend at least two feet below the water and it is probable that it extends several feet below that elevation. The crest width ranges from 15 feet to 27 feet. The spillway is located at the right abutment, and consists of an open concrete channel with concrete retaining walls. The water supply intakes could not be inspected as they are below water and the pipes are buried in the embankment. The outlet pipes were inspected and three pipes were found. Near the toe of the dam, valves were located which are presumably used to control flow through the pipes.

This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past operational performance, Lake Paupackan Dam is judged to be in fair condition. Considering the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between the 1/2 Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF was, in this case, selected as the SDF. The spillway and reservoir, under existing conditions, will pass approximately 19 percent of the PMF before overtopping of the dam occurs. The spillway is, therefore, rated as inadequate.
